I always forget what type of bearings are good and what are bad.  (This 
came up when I was ordering parts recently to build my new work machine.)  
I'll have to remember that sleeve = bad.

Remind me to bring you some old power supplies I have lying around.  I 
probably have some other stuff you'd have fun with too, or be able to use 
for spare parts.

I believe the -5V line has been deleted from recent versions of the ATX 
standard.  (Maybe 2.0?)  My new Enermax supply has no -5V either.  ATX 
has gotten confusing.
